title: Hemi-body port-wine stains and progressive paresis due to territorial perineuriomas.
abstract: We present a case of a biopsy-proven intraneural perineurioma involving the left lumbosacral and brachial plexus with prominent hemi-body port wine stains in the associated dermatomes. The relationship between the two entities is not clear, but this case may provide a clue to understanding the etiological pathogenesis of intraneural perineurioma in the future.
